Fluke 1550C FC 5kV Insulation Tester

High-Voltage Insulation Testing with Wireless Connectivity

The Fluke 1550C FC insulation tester measures insulation resistance up to 5 kV. It supports Fluke Connect® for wireless data sharing, making trend analysis faster and easier in the field.

Safe and Reliable Testing for Industrial Use

Rated for CAT IV 600 V and CAT III 1000 V, it ensures operator safety during high-voltage applications. The device alerts users to live voltages up to 600 V AC/DC before testing.

Flexible Voltage and Automated Analysis

You can select test voltages from 250 V to 5000 V, in 50 V steps up to 1000 V and 100 V steps above. It calculates Dielectric Absorption Ratio and Polarization Index automatically.

Built for Efficiency and Accuracy

With long battery life, it performs up to 750 tests per charge. It stores 99 readings with user-defined labels. A large dual analog/digital display improves visibility in all conditions.
